Title:
WORKPIECE TRACKING METHOD, SYSTEM AND ROBOT
Document Type and Number:
WIPO Patent Application WO/2020/010627
Kind Code:
A1
Abstract:
Provided is a workpiece tracking method, comprising: calibrating a conveyor base coordinate system to obtain a first homogeneous matrix of the conveyor base coordinate system relative to a world coordinate system at an initial moment; calibrating a workpiece coordinate system to obtain a second homogeneous matrix of the workpiece base coordinate system relative to the conveyor base coordinate system at an initial moment; obtaining an advancing speed of the conveyor; calculating a real-time homogeneous matrix of the workpiece coordinate system relative to the world coordinate system by taking the first homogeneous matrix, the second homogeneous matrix and the advancing speed as parameters of the initial moment. The method can reduce the complexity and cost of the workpiece tracking method. Further disclosed are a workpiece tracking system and a robot.
